Often found on the same PCBs as the Toshiba chip (SMI bought the IP or produced compatible versions), the SSS6698 is a USB 3.0 controller. It supports high-speed NAND but is very picky about firmware versions.
The critical connection: Many drives use a hybrid identifier. Tools that detect "TC58NC6623" often require the firmware binary designed for the "SSS6698-BA." If you use the wrong tool, you'll get the dreaded error: "Check Controller Fail" or "Driver Not Matched."
Look for a button labeled "Patch DB" or "Debug" .
An MPTool is a low-level software utility provided by controller manufacturers (like Skymedi/Silicon Motion) to flash drive assemblers.
